How do I program a Valcom Talkback System to work with an SBX320IP telephone system? I'm assuming it uses a CO trunk which I would have to program into a different trunk group than the other trunks. How do I make it possible to access the Talkback
System from the phones? How would I program different zones and use them? What buttons would I put on the phones for this system?
Is this simply an external page button with different zones?
